To all whom it may concern:

llc it known that I, JOHN H. Fox, a citizen of the United States,residing at 228 East One Hundred and 'lwcuty-third street, New York,county of New York, and State of New York, have invented certain new anduseful Improvements in Carbonating Apparatus, fully described andrepresented in thefollowing speci titration and the accompanyingdrawings, forming a par; of the same. or

The present invention relates to an apparatus employing a receptacle inwhich water and carbonic acid absorption of the gas.

The invention consists in various improvements upon the drawingtubc fordrawing off the carbonated water, also in the perforated disks which areused for subdividing or diffusing the gas, and-in means for spacing themapart, and in the arrangement of the above mentioned parts in relationto one another and to the casing of the carbonator.

Heretofore, it has been common to draw the carbonated water from withinthe carbonator by apipc having a comparatively large inlet in which thefree gas could find access and pass to the draft-arm or faucet deal ofsputtering. 'lhe drawing-tube in the presentlinvention is extended intothe Water in thev carbonator and'provided with small perforations whichprevent the admission of large bodies of gas, or cause the gas ifentering the drawing-tube to be finelydivided and mingled with thewater, and thuswholly prevent? sputtering at the drait-arm. Where thetube is thus surrounded by water mingled with gas, and provided withnumerous small perforations, the reduction of pressure within the tubewhich occuis immediately when the draft-arm is opened to draw off theliquid, causes a rapid flow of the water thropgh the perforations, whichflow ontrains the particles of gas which are floating in the Water, andcarries them with the water to the draftarm. The water drawn from suchaperforated drafttube is therefore very sparkling and contains a largeproportion of the as.

Where disks-have been heretofore immersed in water within thecarbonator, they have sometimes been flanged at the edges to supportthem; but when block tin in sheet form is used for the disks theyrequire support at points intermediate to the edges; and such support lavoid in the present invention by means of spiders which may be formedwith central hub, ra-.

diating arms, and a peripheral ring, so as to supportthe disks at thecenter, the margin, and at various intermediate points.

lleretofore, to prevent the displacement of the perforated disks withinthe carbonator durin trans ort-ation, a stop in contact with the casinghas been applied .just below the water level.

rings 0 and the remaining and spokes or arms p to the edges or center ofthe disks; but in theprcsent invention I utilize the drawing-tube tohold the disks in place by extending the tube upwardly from the disksand clamping a collar upon the tube to hold the disks in place.

The invention will be understood by reference to the annexed drawing, inwhich Figure l is a sectional elevation of a carbonator containing boththe disks of the drawing-tube; Fig. 2 is a sectional elevation of acarbonator containing the drawing-tub without the disks and having agasspaco above the water-level; Fig. 3 is a sectional elevation of acarb'onator having 3 casing entirely filled with water; Fig. 4 is a planof one of the perforated disks; Fig. 5 an edge view of the same withoutflanged edge;

and Fig. 6 is a transverse section of the same with one of thesupporting spiders, and the disk formed with a marginal flange. Fig. 7is a plan of one of the spiders; Fig. 8 is an edge view of the same, andFig. 9 an edge view of a modification of the same.

The shell a of the carbonator is form with dome shaped top and itsbottom closed by a base b. An angle-shaped ring 0 and bolts dare shownin Fig. 1 for securing the base to the shell.

A water inlet e is shown provided in Figs. 1 and 2 with a valve fregulated by a float-lever g, to maintain the water at the desiredlevel. v A gas-inlet h is shown,

to which the ordinary gas-distributert' is attached and extended in thebottom of the carbonator with perforations upon its under side todiffuse the gas downwardly.

An outletj is shown in the base b for the carbonated water, and thedrawing-tube is extended upwardly from the same in the center of thecasing, reaching to the top of the shell in Fig. 1; and in Fig. 2terminated Perforations l are shown at various --points in thedrawing-tube.

Eight'disks m are shown in Fig. l of flat form provided with numeroussmall perforations n, as shown in Figs. 1 and 4, the two lower disksbeing separated by disks by the peripheries p and hubs p of the spidersshown in Figs. 7 and 9. Plain rings 0 are employed, as the presence ofthe distributor and of the gas-inlet fixture and water-outlet fixturewould interfere with the arms or hub of the spider. The distributor isin practiceextended from the gas inlet h past one side of thedrawing-tube, as shown in Figs. 1 to 3 inclusive.

The spiders are formed with peripheral ring hub p adapted to looselyencircle the drawing-tube k, attached to the hub and ring p. The armsand the peripheral ring are of uniform depth, but the hub is showninFigs. 1 and 9 a little shallower than the arms, leaving a space at theedge of each hub shown of cylindrical p and at various points inthe'lower part of the casing and. rises through the water, mingling withit and being abthe spiders.

through which the water may gain free access to the holes in thedmwi'ngtube, where they are situated between t disks. To afford suchaccess, the hubs may be made of the same depth as the arms and ring, asshown in Figs. 6 and 8, and provided with perforations q to admit thewater to the holes in the drawing-tube.

To stiffen the pans at the edge, they may be beaded or formed what aslight flange m as shown in Fig. 6, Within which the rings p of thespiders may be inserted. The flange or bead upon the disk is in any casemade of less projection than the distance between the disks, so that theweight of the disks is supported wholly upon A collar r is shown clampedby a set-screw upon the drawing-tube contiguous to the upper disks m,and serves to hold all the disks from displacement.

The drawing-tube in Fig. 1 is shown provided with the perforations l"above the water level. Such -peif'oration is in practice made verysmall, much smaller than can be indicated upon the scaleof the drawing,and such hole operates to'permit a small supply of gas to enter thedrawing-tube to mingle with the water drawn therefrom. It is found inpractice that the gas admitted bysuch a. fine hole does not causesputtering at the draft-arm or faucet, but docs make the water moregaseous.

In Fig. 2, the water level, as with the carbonator in Fig. 1, is kept ata suitable distance below the top of the shell to form a gas chamber,and no puns are shown in this construction, but the drawing-tube isconnected with a water-outlet at one side of the center and is bent tobring it up into the center of the casing so that it will draw the waterfrom all sides. The top of the drawingtube may be terminated in such amachine below the water level, as shown in Fig. 2, and made with orwithout a small perforation Z in the top.

In Fig. 3, the carbonator is shown entirely filled with water Hingsupplied through the water-inlet e from a source of water under suitablepressure.

The gas admitted by the distributor i is discharged sorbed by it. Wherethe gas chamber is provided in the upperpart of the casing, the gaswhich is held in contact with the surface of the water is to some extentabsorbed thereby. The sub-division of the gas by the perforated pans asthe gas rises-upwardly through their numerous small holes, greatlypromotes the discharge of the gas with the water through the smallperforations of the drawing-tube k. Perforated pans have long been usedto diffuse gas in water to promote its absorption, but never inconnection with a drawing-tube having numerous perforations in thewater-space, through which the gas could pass mingled 'with the water.The use of the perforated'drawing-tube extended into the body of wateroperates to draw off with the water small globules of gas which arerising and floating with the water, and such gas and water arethoroughly mingled, so that a large part of the gas thus drawn off isabsorbed in the water in its movement through the drawing-tube and theconveying pipe. I find in practice that this drawing-tube prevents thecontinued'accumulation of the gas in the upper part of the casing, whichoften in the operation of other'carbonators renders it impossible tointroduce a sufficient senses amount of water, and necessitates theblowing off of gas at intervals at the top of the shell, whichnecessarily involves great waste of gas. Theoxtension of thedrawing-tubeupward in the center of the shell through the pan enablesthe drawing-tube to furnish a lock, in conjunction with the collar 2',to hold the pans in place, and perforations formed in the drawingtubebetween the pans also enables the drawing-tube to receive a certainproportion of the gas which is sub-divided in its movement through thepans and is passing upward between the same. The drawing-tube and thepans thus both cooperate to sub-divide the gas and ruinglcit in a finelysub-divided condition with the water, whether in the carbonator shell,the drawing-tube, or the pipe which conveys the carbonated water to thedraft-arm It is obviously immaterial whether the arms p of the spidersare straight, as shown-in the drawing, or crooked.

The gas-inlet h and carbonated watcr-outlot j are both formed asthimbles extended through the bottom of the carbonator and clampedtherein by nuts h and These thimbles are formed with threaded socketsupon their inner ends which face upwardly on the base I) of thecafbonator, and the gasdistributer i and drawing-tube I: are formed withthreaded shanks adapted to screw into their respective threaded sockets.This construction enables the distributor and drawing-tube to be removedforrepairs, and it permits the shank of the distributor to be screwedinto the socket oi the thimble h after the first perforated disk is setin place upon the lower ring 0, the shank of the distributor being bentatn'ght angles, and the first pan being formed with a hole to permit thepassage of the shank through the same, by which it can be screwed intothe socket of the thimble h before the other pans or the shell (1 areset upon the base. Special spiders may be made to support the two lowerpans instead of the plain rings 0 to rest upon the base I by cutting outa portion of the arms of the spiders where the'distributer would intersect the some. The relation of the distributor to the spiders isindicated by the dotted lines tin Fig. which show the distributerextending from the gasinlet h at one side of the center.

It is preferable to locate the drawing-tube in the center of the shella, as shown in Figs. 1 and 2, so as to draw the gas and water equallyfrom all sides; and in building new machines the thimble j for the drawing-tubo may therefore be placed in the center of the base. In applyingmyimpioie'd drawing-tube to ma chines in which the gas-inlet andwater-outlet .art placed near opposite edges of the base,'.thedrawingtube may have a bent shank, {as shown in Fig. 2, to bring theperforated portion of the tube inthe center.

In Fig. 2, the jetsof gas from the holes in the distributor are shownpassing downward behind the hori zontal portion of the drawing-tribewhich is entirely unporforated. -If' the drawing-tube" were perforatcc'!at this point the gas would flow directly into the perforations andwould cause a great deal of sputtering when the liquid was drawnfroin'the di af tfa rm.

By perforating the drawing-tube at various pointe in its height abovethe level of the'disti'ibutcr, thr water .is drawn from difiorentlevelswithin the shell and water in different degrees s'f carbonation is thinmingled together.
